Question

A line that includes the point (1,9) has a slope of 0. What is its equation in slope-intercept form?

Answer 1

y = 9

Explanation:

A line with slope 0 is a horizontal line. Horizontal lines have equation in the form:

y = anumber

We were also given the point on the line (1,9) This is in the form (x,y). So x is 1 and y is 9.

So the equation is

y = 9
